CARSON >> A boxing institution ended its 45-year run Saturday night at the StubHub Center.

The curtain fell on HBO’s long dance with pugilism after the network’s 1,119th fight, a unanimous-decision victory for undisputed women’s welterweight champion Cecilia Braekhus (35-0).Judges at ringside scored the bout 100-90, 100-90, 99-91 for “The First Lady.”

“That’s where I got a little eager,” Braekhus told HBO blow-by-blow announcer Jim Lampley, who was conducting his final interview in that role. “When you are where I am in my career that normally shouldn’t happen, but this is a historical night.”

Braekhus became the first woman champion to appear on HBO in May, when she opened a Gennady Golovkin HBO World Championship Boxing card at the StubHub Center.

Her promoter, Tom Loeffler, called Braekhus’ appearance on HBO one his biggest accomplishments.

“HBO has done an extraordinary job creating stars in boxing,” Loeffler said, “and I’m proud to have worked with these tremendous athletes and very grateful for HBO and their support of the sport of boxing throughout the years.”

The Norwegian boxer is the only woman to hold four major boxing titles at one time, joining Bernard Hopkins, Jermain Taylor, Terence Crawford and Oleksandr Usyk as those to accomplish the feat.

Braekhus’ 147-pound title bout closed HBO’s 18th telecast originating from Carson, where a sparse audience turned out on a chilly night to watch the 176th episode of “Boxing After Dark.”

The televised portion of the card opened with two-time Olympic champion Claressa Shields defending the WBC, IBF and WBA middleweight titles against Belgian boxer Femke Hermans.

Shields, 23, remained perfect as a professional after three judges at ringside each scored a shutout unanimous decision (100-90) for the Flint, Mich., fighter, who improved to 8-0 two years after capturing her second gold medal.

Try as Shields might to put the 28-year-old Hermans (9-2) on the canvas, Shields’ could not avoid her sixth decision victory, four of which took place in 2018.

The Olympian watched from ringside as Braekhus went about her business in the main event.

The Norwegian said she was more interested in boxing UFC featherweight champion Cris Cyborg, who accompanied Shields to the ring on Saturday, than meeting the Olympian.
